1. An image rendering device, comprising:
a first sensor, configured to sense a target object in a three-dimensional (3D) mode to generate a first 3D-depth-signal, and sense the target object in a two-dimensional (2D) mode to generate a first surface-color-signal;
a second sensor, configured to sense the target object in the 3D mode to generate a second 3D-depth-signal, and sense the target object in the 2D mode to generate a second surface-color-signal;
an infrared ray (IR) projector, configured to generate an IR dot pattern; and
a processor, configured to control the IR projector to project the IR dot pattern on the target object in the 3D mode, and process the first surface-color-signal, the second surface-color-signal, the first 3D-depth-signal and the second 3D-depth-signal to obtain a color 3D model of the target object.
